Google users can still send subscription requests to contacts whose
accounts are hosted elsewhere. But they cannot accept incoming
requests. This change is akin to Google no longer accepting incoming
e-mail for @gmail.com addresses from non-Google domains. That would be
unthinkable.

The GNU/FSF servers are moving between February 22nd and March 1st, 2012. There will be service interruptions during that period. There will be a multi-hour outage for most services on February 28th, 2012, starting at 10am EST (UTC/GMT -5).

The GNU list server is a monster machine serving lists.gnu.org, lists.nongnu.org and a few other domains. Every day, it spools out over 1 million messages for 2700 mailing lists. Until April 11, our venerable list server was an 8-year old Fedora Core 2 (!) box equipped with 6 high-speed SCSI drives organized in two RAID packs to maximize I/O bandwidth.
These drives were incessantly cranking every day, as Mailman forwarded
incoming posts to thousands of subscribers over a saturated
T1 uplink at the FSF headquarters.
